I can't view my website, charleymyers.net

Because it doesn't exist: who.is/whois/charleymyers.net

What happened to my website. do I need to update my subscription/ other? Find a new browser? My site has been up for years.

Are you sure the vendor you've used to host it, pay for domain fees etc. didn't go out of business or similar? The domain you posted is not even registered at this point (in other words… must have gone through several grace periods after being unpaid, then stayed protected at the registrar… and since it's available to register at this point it must be out of order for months by now…)
